T 1r/ZZ 1071/0771, it may concer-71,:

Be it known that I, THOMAS A. GLENDIN- NING, a citizen of the UnitedStates, residing in Manhattan borough, city of New York, in the countyof New York and State of New York,have invented certain new and usefulImprovements in Temporary Binders, of which the following is aspecification.

This invention relates to means for temporarily binding or otherwiseholding a set of papers, leaves, cards, or the like; and its principalobject is to prevent the temporary binder or holder from being tamperedwith and one or more papers, sheets, cards, or the likeremoved orinserted without the knowledge of the one in charge of the binder.

To this end I contrive means whereby the device which binds or holds theleaves or other devices may be operated only by a speciallytitted key,so that when the leaves are clamped and the key removed it is diflicultor impossible to operate the mechanism for the purpose of removing orinserting a leaf, except by one having aspecial key, it being intendedthat each of the binders made according to my invention shall haveindividual keys, the keys of each binder different from the keys of theothers. Y

In the drawings forming part of this specitication, Figure 1 is an endviewotl a temporary binder having my improvements applied thereto. Fig.2 is a View at one end of the binder, showing the preferred connectionbetween the key-cylinder and the leaf-binding rod. Fig. 3 is a sectiontaken on line of Fig. 7. Fig. 4 is a fragment of a leaf, Showing one ofits openings, whereby it is impaled upon a series of rods used in thebinder. Fig. 5 is a perspective view of a connector seen at Fig. 2. Fig.6 is a perspective view of a housing for the key-cylinder and itslocking-tumblers; and Fig. 7 is a general view of a temporary binderhaving my improvements applied thereto and shown partlyin section, theleaves being removed. l

In the several views like signs denote like parts.

The binder illustrated in this instance comprises a back or framework 1,having at its ends flanges 2 and 3, between which extend longitudinalclamps 4 and 5 for binding the sheets or leaves 6, said clamps 4 and 5being formed upon the edges of longitudinal cheekpieces 7 and8,respectively,which curve within the main frame or back 1 of thebinder, as seen at Fig. 3, and at their ends are provided withinwardly-projecting guide extensions 9 and 1,0, which work between saidback l and guide-plates 11 and 12, attached to the back at itsextremities by rivets 13, as seen at the right hand of Fig. 7. Theclamps may thus be moved toward or away from each other in said guidingmeans for accommodating thin or thick packs of leaves.

A central rod 15 extends longitudinally ot' the clamping-jaws 4 and 5and is provided at its ends with right and left screw-threads 16 and 17,the threaded portions of the rod being engaged by nuts 18 and 19,respectively, each nut being connected by links 2O to the oppositeclamping-jaws, so that upon revolution of the rod the nuts are movedsimultaneously either toward the end ofthe rod or else toward the middleportion thereof, the action of the links 2O being to open or close theclampingjaws 4 and 5. Said threaded rod is rotatably mounted in bearings21 and 22, provided upon the frame at the central portion of the binder,and is provided with a collar 23 coniined between' said bearings,whereby endwise play ofthe rod is prevented. The frame is provided withribs 24, one on each Side of the rod, for guiding the nuts 18 and 19,each of which has a portion 25 protruding ybetween said ribs, as seen atFig. 3. v Uponone end ofthe rod is provided a collar 26, having a lug.27, and at this end of the rod is provided a cylinder 28, having a l-ug29 for coperation with the lug 27. Said cylinder is mounted within ahousing 30, having a lateral extension 31, which is secured by a screw32 or otherwise upon xed plate`12. Said cylinder extends through saidhousing, having at its inner end a cap 33 and at its outer end a head34, whereby longitudinal displacement is prevented. The lug 29 ispreferably formed upon said cap 33. In said cylinder is an irregularkeyhole 35, in which is removably fitted a key 36, said key being shownin crosssection at Fig. 1 and being adapted to turn IOO the cylinder toan unlimited extent, whereby by the cooperation of the lug 29 with thelug 2T the rod l5 is turned for either binding or releasing the jaws 4and 5. WVithin the cylinder are provided pin-tumblers 37, and within theextension 3l of the housing are mounted cooperative pin-tumblers 38,operated by compression-springs 39, said tumblers being released by thekey 36, so as to permit rotation of the cylinder to effect the turningof the rod 15. At Fig. 7 the tumblers are shown in their releasedpositions; but it will be understood that when the key is withdrawn thesprings 39 press the tumblers 38 into the tumbler-holes 40 in thecylinder, so as to lock the same, whereby removal of the sheets 6 whenthey are once clamped by the jaws 4 and 5 is prevented, as is also theinsertion of new sheets. The tumblers are intended to be differentlyarranged in different binders, so that leach requires its individualspecially-fitted rey.

lf the lug 27 is in a position to come directly in contact with the lug29 after the key has rotated the screw-shaft in one direction asuiiicient amount-as, for instance, to bind or clamp the leaves inposition#a point may be reached where the key cannot be turned fartherin that direction and that the key will be at a position where it willbe impossible, owing to the organization of the class of lock which isemployed, to withdraw the key from the lock. Consequently the key mustbe turned backward until it comes to the position where it may bewithdrawn. This organization of lugs permits the key to turn backwardnearly a complete revolution; but there are instances where the key mayturn the screw up to the point at which it is desired to be left, but atsuch a position that to turn the key back to its point of removal wouldslightly loosen the clamping action upon the sheets. 1n many instances(and, in fact, generally) a slight loosening or tightening', as the casemay be, to bring the key to this particular position would not interferewith the proper action of the device; but there are instances andcertain employments where it will be found necessary to avoid thisfeature, and means for so doing are illustrated in Figs. 2 and 5. Fig. 5shows a connector in the form of a tumbler organized to admit a greateramount of idle movement than that of the organization previouslydescribed and is shown as comprising a body 44, bored at 45 to fit uponan extension 46 of the screw-rod l5 and having lugs 47 and 48, theformer to engage the lug 29 of the cylinder and the latter to engage thelug 27 of the screw-rod. The connector is introduced, so as to increasethe range of rotation of the cylinder independently of the screwrod, sothat the said cylinder can be turned more than one revolutionindependently, thus insuring the ready release of the key from thecylinder after clamping the sheets or leaves.

l l l l l l l l Telescoping rods 49 and 50 arc provided between theclamps 4 and 5, and each leaf is preferably provided with a key-slot 5l,Fig. 4, to facilitate impaling upon and removal from said rods.

Variations may be resorted to within the scope of my invention, andportions of my improvements may be used without others. My invention maybe applied to other devices than temporary binders, and many variationsin the forms of the special keys and keyholes and wards and tumblers maybe resorted to within the scope of my improvements, so long as eachbinder or the like is provided with its own special key, which may beoperated to lock or secure its leaves, but is not adapted to tit thekeyholes of other similar binders or holders. Both ends of the bindermay be formed, as shown at Fig. 2, so that it is necessary to employ twokeys, one fitted to each cylinder, to release the binding mechanism, sothat so long as both keys are in place either key may be turned toeffect the rotation of the threaded rod. The keys may be diiferent onefrom the other, so that each can release only the lock to which it isspeciallylitted, and when the keys are in the possession of differentpersons both must be present in order to enable a leaf to be removed,thereby increasing the security afforded by locking the leaf-bindingmechanism. Other tumbler-locks than that herein illustrated may be used,and so long as tumblersare used in such a way that only the person incharge is able to unclamp the leaves the structure is within the scopeof my invention.

Having thus described my invention, claiml l. The combination with meansto releasably hold a set of leaves or the like, including a member tosecure the leaves, of means to effect movement of said securing meansand embodying key-controlled tumblers, and a connecting-tumbler havingan amount of idle movement.
